Tkinter图像标签，除了最后一个

Question

我遇到的问题是相同的图像（在标签中）将不会显示，除了最终的标签。这是一张图片，告诉你我的意思。在这张图片中，我生成了7张卡片，然后生成了2张。我希望空白处用问号填充。

可创建的卡的最大数量范围为0-8。如果我生成6张卡片，然后生成4张卡片，我希望卡片5-6变成随机卡片图像。在

卡片类

import tkinter as tk
from PIL import Image, ImageTk
class Card:
    def __init__(self, name, imageURL, cardType, rarity):
        self.name = name
        self.imageURL = imageURL
        self.cardType = cardType
        self.rarity = rarity
    def __repr__(self):
        print(self.name)
    def __str__(self):
        return self.name
    def returnImage(self):
        self.timage = Image.open(self.imageURL)
        if not self.timage.size == (212,263):
            self.timage = self.timage.resize((212,263), Image.ANTIALIAS)
        self.tphoto = ImageTk.PhotoImage(self.timage)
        return self.tphoto
    def createLabel(self, parent):
        self.timage = Image.open(self.imageURL)
        if not self.timage.size == (212,263):
            self.timage = self.timage.resize((212,263), Image.ANTIALIAS)
        self.tphoto = ImageTk.PhotoImage(self.timage)
        self.cardLabel = tk.Label(parent, image = self.tphoto)
        self.cardLabel.image = self.tphoto
        return self.cardLabel

这是创建窗口后我的代码的顶部。每个标签与我要显示的图像都正确显示。比如这里：

我的尝试

每次按下按钮，卡片都会被选中并显示出来。此代码也会运行。我也尝试过将标签设置为randomCard.createLabel（root）但是同样的事情发生了。在

def randomizeButton():
    global currentCards,card1Label, card2Label,card3Label,card4Label,card5Label,card6Label,card7Label,card8Label
    currentCards = maxCards
    setMax()
    randomizeCards()
    print('Current Cards: ' + str(currentCards))
    if(maxCards == 0):
        card1Label.configure(image = randomCard.returnImage())
        card2Label.configure(image = randomCard.returnImage())
        card3Label.configure(image = randomCard.returnImage())
        card4Label.configure(image = randomCard.returnImage())
        card5Label.configure(image = randomCard.returnImage())
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 1):
        card2Label.configure(image = randomCard.returnImage())
        card3Label.configure(image = randomCard.returnImage())
        card4Label.configure(image = randomCard.returnImage())
        card5Label.configure(image = randomCard.returnImage())
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 2):
        card3Label.configure(image = randomCard.returnImage())
        card4Label.configure(image = randomCard.returnImage())
        card5Label.configure(image = randomCard.returnImage())
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 3):
        card4Label.configure(image = randomCard.returnImage())
        card5Label.configure(image = randomCard.returnImage())
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 4):
        card5Label.configure(image = randomCard.returnImage())
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 5):
        card6Label.configure(image = randomCard.returnImage())
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 6):
        card7Label.configure(image = randomCard.returnImage())
        card8Label.configure(image = randomCard.returnImage())
    if(maxCards == 7):
        card8Label.configure(image = randomCard.returnImage())

标签设置在网格中。在

card1Label.grid(row = 0, column = 0)
card2Label.grid(row = 0, column = 1)
card3Label.grid(row = 0, column = 2)
card4Label.grid(row = 0, column = 3)
card5Label.grid(row = 1, column = 0)
card6Label.grid(row = 1, column = 1)
card7Label.grid(row = 1, column = 2)
card8Label.grid(row = 1, column = 3)

如果你需要更多的信息，我很乐意提供。我尽力提供所有必要的信息。在

Tkinter只允许每个映像实例使用一次。要多次显示同一图像，需要为每个标签分别加载图像。在

例如，如果要将同一图像显示5次，则需要运行如下代码：

import tkinter
root = tkinter.Tk()
image1 = tkinter.PhotoImage(file=icon.gif)
label1 = tkinter.Label(root, image=image1)
label1.pack()
image2 = tkinter.PhotoImage(file=icon.gif)
label2 = tkinter.Label(root, image=image2)
label2.pack()
image3 = tkinter.PhotoImage(file=icon.gif)
label3 = tkinter.Label(root, image=image3)
label3.pack()
image4 = tkinter.PhotoImage(file=icon.gif)
label4 = tkinter.Label(root, image=image4)
label4.pack()
image5 = tkinter.PhotoImage(file=icon.gif)
label5 = tkinter.Label(root, image=image5)
label5.pack()

显然，这只是一个例子，并没有在代码中使用变量名或类。在
